UV –HK939
UV/Visible light cure Adhesive 紫外/可见光固化胶粘剂
PRODUCT DESCRIPTION 产品介绍
UV-HK939 is one component, high viscosity, thixotropic adhesive. The material cures when exposed to ultraviolet radiation and/or visible light. It has excellent adhesion to a variety of substrates such as glass, many plastics, rubbers and metals. It is formulated for adhesion to “difficult to bond” substrates, such as noryl, acetal, polyether plastics, and ferrites, etc. The cured bond joint possess high adhesive strength, toughness and excellent durability. UV-HK939是一种单组分，高粘度，具触变性的粘接剂。它可在紫外和（或）可见光辐照下固化。它对玻璃，各种塑料和金属等多种基质具有良好的粘附性能。UV-HK939专门针对一些难粘接性基质所配制，例如改性聚苯醚，缩荃，聚醚塑料，陶铁磁体等。该产品固化后具有强度高，粘性好和极佳的耐久性。
UV-HK939 is available in natural color and black version (UV-HK939B) 可提供自然色（UV-HK939）和黑色（UV-HK939B）两种产品。

DIRECTIONS FOR USE 使用指南
The adhesive can be hand applied from bottle, or dispensing systems are also available for high volume assembly applications. 该产品可手工从瓶中取出使用，对于大体积的装配生产可提供分散系统。
Apply adhesive to one surface, bring parts together and expose to UV-light. Alternatively, parts can be assembled and then adhesive applied & allowed to wick around the joint area before curing. 将该产品施加在一个部件的表面上，将需粘接的部件合紧后用紫外光辐照。也可以先将部件装配后再将胶粘剂施加到需粘接的中心区域。
Curing time table 固化进度表
The material cures when exposed to ultraviolet radiation and/or visible light with sufficient intensity. Recommended intensity for cure is 30 mW/ cm2 at 365 nm. For dry curing of exposed surfaces, higher intensity UV is required, e.g. 100 mW/ cm2 minimum.在足够强度的紫外和（或）可见光辐照下该产品可固化。推荐固化光强度为30 mW/ cm2 at 365 nm。对于外露表面的干养护，推荐使用更高强度的紫外光，如至少100 mW/ cm2。
STORAGE INFORMATION 储存方法
Store at 8 – 20 °C in a dry, cool place and in sealed containers out of direct sunlight. 在8 – 20 °C下干燥，凉爽和密封保存，避免阳光的直接照射。
